Introducción: La deshidratación hipernatrémica neonatal es un problema creciente, en la que la alimentación y los conocimientos sobre cuidados del recién nacido juegan un papel primordial. Objetivo: Determinar los factores de riesgo asociados a la deshidratación hipernatrémica en neonatos. Métodos: Estudio observacional descriptivo retrospectivo en una población de 20 neonatos con deshidratación hipernatrémica ingresados en el servicio de cuidados intermedios de un hospital de Lima, Perú entre junio 2017- septiembre 2018. Todos tenían concentraciones de sodio sérico≥150 mmol/L. La recolección de la información se extrajo de las historias clínicas. Resultados: De los 20 neonatos con deshidratación hipernatrémica; los nacidos por cesárea equivalen a 30 por ciento, mientras que por parto vaginal, a 70 por ciento de los casos. Se demostró que hay una relación inversa entre número de gestación y concentraciones de sodio al ingreso, sin embargo, no hubo significación estadística. Se logró una disminución entre sodio de entrada y su primer control, con una media de disminución de 0,57 meq/L/h. Clínicamente los neonatos afectados desarrollaron en mayor porcentaje ictericia y fiebre. No se encontró relación significativa entre el resto de los factores asociados. Conclusiones: Entre los factores de riesgo asociados a la deshidratación hipernatrémica, destaca que el grupo nacidos por cesárea fue menor que los nacidos por parto vaginal, lo que influye en el número de altas precoces al nacimiento. Ictericia y fiebre continúan siendo las características clínicas que debe identificarse tempranamente. Se trata de un cuadro prevenible si se brinda adecuada información a la madre sobre cuidado neonatal(AU)
Introduction: Neonatal hypernatremic dehydration is a growing problem, in which feeding and knowledge about newborn care play a key role. Objective: To determine the risk factors associated with hypernatremic dehydration in neonates. Methods: Retrospective descriptive observational study in a population of 20 neonates with hypernatremic dehydration admitted to the intermediate care service of a hospital in Lima, Peru between June 2017 and September 2018. All of them had serum sodium concentrations≥150 mmol/L. The collection of information was extracted from medical records. Results: Of the 20 neonates with hypernatremic dehydration, those born by cesarean section are equivalent to 30 , while by vaginal delivery, 70% of cases. It was shown that there is an inverse relationship between gestation number and sodium concentrations at admission, however, there was no statistical significance. A decrease was achieved between input sodium and its first control, with a mean decrease of 0.57 meq/L/h. Clinically, the affected neonates developed a higher percentage of jaundice and fever. No significant relationship was found between the rest of the associated factors. Conclusions: Among the risk factors associated with hypernatremic dehydration, it stands out that the group born by cesarean section was lower than those born by vaginal delivery, which influences the number of early discharges at birth. Jaundice and fever continue to be the clinical features that should be identified early. This is a preventable condition if adequate information is provided to the mother about neonatal care(AU)

Primary adipsia is a rare condition in which there is failure in the activation threshold of the hypothalamic osmoreceptors, leading to osmolality imbalance. Here, we reported the case of a Pit Bull dog with an altered level of consciousness (started after weaning) and adipsia. There was an increase in plasma osmolality (444 mOsm/kg), sodium (223.7 mg/dL), and chlorine (173 mg/dL) levels. Based on the suspicion of primary adipsia, water was administered via a nasogastric tube, with clinical improvement. The owner was instructed to supply water with food. Eight months after discharge, the dog returned with parvovirus and died. In the anatomopathological examination, no structural changes were observed in the central nervous system. To our knowledge, this is the first report of hypernatremia due to adipsia in a Pit Bull dog, showing that this is a differential diagnosis that should be considered in this breed.
Adipsia primária é uma rara condição em que há falha no limiar de ativação dos osmoreceptores hipotalâmicos, levando ao desequilíbrio da osmolalidade. Este artigo tem como objetivo relatar o caso de um cão da raça Pit Bull apresentando alteração no nível de consciência (iniciado após o desmame) e adipsia. Foi verificado aumento da osmolalidade plasmática (444 mOsm/kg), sódio (223,7 mg/dL) e cloro (173 mg/dL). Baseado na suspeita de adipsia primária, iniciou-se administração de água via sonda nasogástrica, com melhora clínica. O tutor foi orientado a fornecer água junto a alimentação. Oito meses após alta, o paciente retornou com parvovirose e veio a óbito. No exame anatomopatológico, não foram observadas alterações estruturais no sistema nervoso central. Este é o primeiro relato de hipernatremia por adipsia em um cão Pit Bull, mostrando que este é um diagnóstico diferencial que deve ser considerado nesta raça.

Introduction: Coronavirus disease 2019 (COVID-19) pandemic spread rapidly, creating a worrisome scenario worldwide. In hospitalized patients, dysnatremia (hyponatremia and/or hypernatremia) is the most common electrolyte disturbance, reported in 3040% of cases and associated with a poor prognosis. This study aimed to evaluate the association between dysnatremia and mortality in hospitalized patients infected with SARS-COV-2. Methods: Retrospective longitudinal study that analyzed data from hospital records of 1,000 patients with COVID-19 (median age, 62.5 years; 57.1% men), including 109 (10.9%) deaths. Kaplan-Meier survival curves and Cox proportional hazard models with Hazard Ratio (HR) with 95% confidence intervals (95%CI) were applied to confirm the association between dysnatremia (hyponatremia and/or hypernatremia) and death. Results: Hypernatremia was detected in 83 (76.1%) of the patients who died, with a cumulative reduction in survival (p < 0.01) and a 2.42-fold increased mortality risk (95%CI: 1.452.91). In the multivariable analysis, hypernatremia was the main factor associated with increased mortality (HR: 1.50; 95%CI: 1.231.81). Long length of stay (LOS) (HR: 1.54; 95%CI: 1.211.78), old age (HR: 1.63; 95%CI: 1.281.88), and chronic kidney disease (HR: 1.77; 95%CI: 1.213.30) were also associated with death. Conclusion: Hypernatremia during hospitalization is an important risk factor for poor prognosis and an increased mortality risk. LOS, old age, and chronic kidney disease could also be used for risk stratification in patients with COVID-19.

O tratamento de desidratação e distúrbios eletrolíticos graves é contraindicado por meio de hipodermóclise, mas o nível de evidência da recomendação se baseia na opinião de especialistas. Descreve-se caso clínico de paciente com idade avançada, com indicação de cuidados paliativos, que evoluiu com desidratação hiperosmolar com hipernatremia grave, injúria renal aguda e hipercalemia. Tratou-se a paciente com solução hipotônica por meio da técnica de hipodermóclise, com resolução completa do quadro. Conclui-se que há necessidade de mais estudos sobre o uso da hipodermóclise para o tratamento de distúrbios hidroeletrolíticos graves.
The treatment of dehydration and severe electrolyte disturbances using hypodermoclysis is usually contraindicated, but the level of evidence for its recommendation is based on expert opinion. This case report describes an older patient receiving palliative care who developed hyperosmolar dehydration with severe hypernatremia, acute kidney injury, and hyperkalemia. She was treated with hypodermoclysis using a hypotonic solution, which led to complete resolution of the condition. In conclusion, further studies on the use of hypodermoclysis for the treatment of severe hydroelectrolytic disorders are needed.

Abstract Hypernatremia is a common electrolyte problem at the intensive care setting, with a prevalence that can reach up to 25%. It is associated with a longer hospital stay and is an independent risk factor for mortality. We report a case of hypernatremia of multifactorial origin in the intensive care setting, emphasizing the role of osmotic diuresis due to excessive urea generation, an underdiagnosed and a not well-known cause of hypernatremia. This scenario may occur in patients using high doses of corticosteroids, with gastrointestinal bleeding, under diets and hyperprotein supplements, and with hypercatabolism, especially during the recovery phase of renal injury. Through the present teaching case, we discuss a clinical approach to the diagnosis of urea-induced osmotic diuresis and hypernatremia, highlighting the utility of the electrolyte-free water clearance concept in understanding the development of hypernatremia.
Resumo A hipernatremia é um distúrbio eletrolítico comum no ambiente de terapia intensiva, com uma prevalência que pode chegar a 25%. Está associada a maior tempo de internação hospitalar e é um fator de risco independente para a mortalidade. Este relato ilustra um caso de hipernatremia de origem multifatorial no ambiente de terapia intensiva. Destacaremos o papel da diurese osmótica por geração excessiva de ureia, uma causa de hipernatremia pouco conhecida e subdiagnosticada. Este cenário pode estar presente em pacientes em uso de elevadas doses de corticoides, com sangramento gastrointestinal, em uso de dietas e suplementos hiperproteicos e estado de hipercatabolismo, especialmente durante a fase de recuperação de injúria renal. A seguir, discutiremos uma abordagem clínica para o diagnóstico da hipernatremia secundária à diurese osmótica induzida por ureia, destacando a importância do conceito de clearance de água livre de eletrólitos nesse contexto.

Abstract Objective: To evaluate the association between dysnatremias or dyschloremias and mortality during hospitalization in patients with acute kidney injury (AKI) or chronic kidney disease (CKD) undergoing acute hemodialysis. Methods: We carried out a retrospective cohort study on adult patients undergoing acute hemodialysis with AKI or CKD diagnosis at a public hospital in Lima, Peru. Dysnatremias were categorized as hyponatremia (Na < 135mmol/L) or hypernatremia (Na > 145mmol/L), and dyschloremias were defined as hypochloremia (Cl < 98 mmol/L) or hyperchloremia (Cl > 109mmol/L). The outcome of interest was mortality during hospitalization. We performed generalized lineal Poisson family models with bias-corrected and accelerated non-parametric bootstrap to estimate the risk ratios at crude (RR) and adjusted analysis (aRR) by gender, age, HCO3 (for all patients) and Liaño score (only for AKI) with CI95%. Results: We included 263 patients (mean age: 54.3 years, females: 43%): 191 with CKD and 72 with AKI. Mortality was higher in patients with AKI (59.7%) than in patients with CKD (14.1%). In overall, patients with hypernatremia had a higher mortality during hospitalization compared to those who had normal sodium values (aRR: 1.82, 95% CI: 1.17-2.83); patients with hyponatremia did not have different mortality (aRR: 0.19, 95% CI: 0.69-2.04). We also found that hyperchloremia (aRR: 1.35, 95% CI: 0.83-2.18) or hypochloremia (aRR: 0.66, 95% CI: 0.30-14.78) did not increase mortality in comparison to normal chloride values. No association between dysnatremias or dyschloremias and mortality during hospitalization was found in CKD and AKI subgroups. Conclusions: In our exploratory analysis, only hypernatremia was associated with mortality during hospitalization among patients with AKI or CKD undergoing acute hemodialysis.
Resumo Objetivo: Avaliar a associação entre distúrbios do sódio ou do cloro e mortalidade hospitalar de pacientes com insuficiência renal aguda (IRA) ou doença renal crônica (DRC) submetidos a hemodiálise aguda. Métodos: O presente estudo de coorte retrospectiva incluiu pacientes adultos submetidos a hemodiálise aguda com diagnóstico de IRA ou DRC em um hospital público de Lima, Peru. Os distúrbios do sódio foram classificados como hiponatremia (Na < 135mmol/L) ou hipernatremia (Na > 145mmol/L), enquanto os distúrbios do cloro foram classificados como hipocloremia (Cl < 98 mmol/L) ou hipercloremia (Cl > 109mmol/L). O desfecho de interesse foi mortalidade hospitalar. Utilizamos modelos de Poisson da família de modelos lineares generalizados com bootstrap não-paramétrico e correção de viés acelerado para estimar os riscos relativos na análise bruta (RR) e ajustada (RRa) para sexo, idade, HCO3 (para todos os pacientes) e escore de Liaño (apenas para IRA) com IC 95%. Resultados: Foram incluídos 263 pacientes (idade média 54,3 anos; 43% do sexo feminino), 191 com DRC e 72 com IRA. A mortalidade foi mais elevada nos pacientes com IRA (59,7%) do que nos indivíduos com DRC (14,1%). No geral, os pacientes com hipernatremia tiveram mortalidade hospitalar mais elevada do que os indivíduos com valores normais de sódio (RRa: 1,82; IC 95%: 1,17-2,83). Os pacientes com hiponatremia não apresentaram mortalidade diferente (RRa: 0,19; IC 95%: 0,69-2,04). Também identificamos que hipercloremia (RRa: 1,35; IC 95%: 0,83-2,18) e hipocloremia (RRa: 0,66; IC 95%: 0,30-14,78) não elevaram a mortalidade em comparação a indivíduos com níveis normais de cloro. Não foi encontrada associação entre distúrbios do sódio ou do cloro e mortalidade hospitalar nos subgrupos com DRC e IRA. Conclusões: Em nossa análise exploratória, apenas hipernatremia apresentou associação com mortalidade hospitalar em pacientes com IRA ou DRC submetidos a hemodiálise aguda.

ABSTRACT Objective: The literature indicates a single universal cut-off point for weight loss after birth for the risk of hypernatremia, without considering other factors. The aim of this study was to construct and internally validate cut-off points for the percentage weight loss associated with the risk of hypernatremia, taking into account risk factors. Methods: A prospective study with a three-day follow-up was conducted in 165 neonates with a gestational age ≥35 weeks. The main outcome variable was mild or moderate hypernatremia (serum sodium ≥ 145 mmol/L). Secondary variables (risk factors) were maternal and infant variables. A multivariate logistic regression model was constructed to predict hypernatremia, obtaining its probability and the optimal discriminant cut-off point for hypernatremia (receiver operating characteristic analysis). Based on this point, threshold weight loss values were obtained according to the other variables. These values were internally validated by bootstrapping. Results: There were 51 cases (30.9%) of hypernatremia. The mean percentage weight loss for hypernatremic infants was 8.6% and 6.0% for the rest. Associated variables in the multivariate model included greater weight loss, male gender, higher education level, multiparity, and cesarean delivery. The model had an area under the receiver operating characteristic curve of 0.84 (sensitivity = 77.6%; specificity = 73.2%). Similar values were obtained in the bootstrapping validation. The lowest percentage weight loss was 4.77%, for cesarean delivery in male infants of mothers with a higher education level. Conclusions: The weight loss percentage values depended on the type of delivery, parity, newborn gender, and level of maternal education. External studies are required to validate these values.
RESUMO Objetivo: A literatura indica um único ponto de corte universal na perda de peso após o nascimento para risco de hipernatremia, sem considerar outros fatores. Nosso objetivo foi criar e validar internamente pontos de corte para o percentual de perda de peso associado ao risco de hipernatremia considerando fatores de risco. Métodos: Foi feito um estudo prospectivo que incluiu 165 neonatos com idade gestacional ≥ 35 semanas, acompanhados por três dias. A principal variável de resultado foi hipernatremia leve ou moderada (sódio sérico ≥ 145 mmol/L). As variáveis secundárias (fatores de risco) foram variáveis maternas e dos neonatos. Um modelo multivariado de regressão logística foi criado para diagnosticar hipernatremia, obteve sua probabilidade e o ponto de corte discriminativo ideal para hipernatremia (análise da Característica de Operação do Receptor). Com base nesse ponto, obtivemos então os valores limites de perda de peso de acordo com as outras variáveis. Esses valores foram internamente validados por. Resultados: Há 51 casos (30,9%) de hipernatremia. O percentual de perda de peso para neonatos hipernatrêmicos foi 8,6% e 6,0% para o restante. As variáveis associadas no modelo multivariado incluíram maior perda de peso, sexo masculino, maior nível de escolaridade, multiparidade e cesárea. O modelo apresentou uma área sob a curva da Característica de Operação do Receptor de 0,84 (sensibilidade = 77,6%; especificidade = 73,2%). Valores semelhantes foram obtidos na validação da bootstrapping. O menor percentual de perda de peso foi 4,77% para cesárea em neonatos do sexo masculino de mães com maior nível de escolaridade. Conclusões: Os valores percentuais de perda de peso dependem do tipo de parto, paridade, sexo do recém-nascido e nível de escolaridade materna. São necessários estudos externos para validar esses valores.

Adipsic hypernatremia is a rare disease where patients do not feel thirst even in the increased serum osmotic pressure and results in electrolyte imbalance, severely increased osmotic pressure and neurologic symptoms like nausea, vomiting, and seizures. We report a 12-year-old male patient who had underwent a trans-sphenoidal surgery for craniopharyngioma newly diagnosed with adipsic hypernatremia after having growth hormone replacement for growth hormone deficiency. The patient visited emergency room complaining of generalized weakness, tremor in both legs, and poor oral intake including water after starting growth hormone replacement therapy. Laboratory test revealed serum sodium 168 mmol/L and serum osmolality 329 mOsm/kg, despite the patient didn't feel any thirst at all. We treated him with scheduled water intake of 2.5 L a day with intranasal vasopressin. He admitted to Soonchunhyang University Gumi Hospital and Soonchunhyang University Seoul Hospital for 4 times during the following 8 months and serum sodium level and osmolality was controlled by scheduled water intake combined with intranasal vasopressin treatment. It is still unclear whether growth hormone replacement worked as a trigger of hypernatremia.

OBJETIVOS: Relatar o caso de um recém-nascido com deficiência de glicerol quinase, no qual foi identificada uma mutação isolada ainda não descrita no gene GK. DESCRIÇÃO DO CASO: Um recém-nascido com 10 dias de vida foi trazido ao serviço de urgência por recusa alimentar com 24 horas de evolução. Ao exame físico apresentava perda de 31% do peso de nascimento e sinais de desidratação. Os exames laboratoriais constataram presença de acidose metabólica com anion gap aumentado, creatinina 2,41mg/dL, ureia 306 mg/dL, hipernatremia (182mEq/L), hipercalemia (6,8mEq/L), hipercloremia (151mEq/L), transaminase glutâmico-oxalacética 879U/L, transaminase glutâmico-pirúvica 243U/L, triglicerídeos 725mg/dL. A cromotagrafia de ácidos orgânicos revelou hiperglicerolemia e glicerolúria compatíveis com deficiência de glicerol quinase. O estudo genético revelou uma mutação ainda não descrita: c.187T>C (p.S63P) em hemizigotia no gene GK. CONCLUSÕES: A causa mais frequente de desidratação hipernatrêmica no período neonatal é a hipogalatia materna. Nos casos mais graves de desidratação outras etiologias devem ser consideradas, incluindo causas metabólicas como a deficiência de glicerol quinase. Neste caso foi encontrada uma mutação no gene GK ainda não descrita.
AIMS: To report the case of a newborn with glycerol kinase deficiency, in which an isolated mutation not yet described in the GK gene was identified. CASE DESCRIPTION: A neonate with 10 days of age was brought to the emergency department for refusal to feed with 24 hours of evolution. Physical examination showed a loss of 31% of birth weight and signs of dehydration. Laboratory tests revealed a metabolic acidosis with increased anion gap, creatinine 2.41mg/dL, urea 306mg/dL, hypernatremia (182mEq/L), hyperkalemia (6.8mEq/L), hyperchloremia (151mEq/L), glutamic-oxalacetic transaminase 879U/L, glutamic-pyruvic transaminase 243U/L, triglycerides 725mg/dL. Chromotagraphy of organic acids revealed hyperglycerolemia and glyceroluria compatible with glycerol kinase deficiency. The genetic study revealed a mutation not yet described: c.187T>C (p.S63P) as hemizygote status in the GK gene. CONCLUSIONS: The most frequent cause of hypernatremic dehydration in the neonatal period is maternal hypogalactia. In more severe cases of dehydration, other etiologies should be considered, including metabolic causes such as glycerol kinase deficiency. In this case a mutation not yet described in the GK gene was found.

RESUMEN Antecedentes: La incidencia de la diabetes insípida gestacional es aproximadamente 1/30.000 gestaciones. Objetivo: A propósito de un caso de diabetes insípida gestacional ocurrida en nuestra unidad, se decide comunicar y revisar la literatura referente a opciones de manejo y tratamiento del mismo. Caso clínico: Mujer de 38 años, primigesta de 32 semanas con clínica de poliuria y polidipsia con una ingesta hídrica diaria de hasta 7 litros. Tras realizar las pertinentes exploraciones complementarias y descartar otras patologías más frecuentes, se establece el diagnóstico de diabetes insípida gestacional. Conclusiones: La diabetes insípida gestacional es una entidad muy poco frecuente que puede desencadenar en un estado de deshidratación intensa con hipernatremia y su consecuente afectación neurológica. Es importante el diagnóstico precoz para evitar las complicaciones tanto a nivel materno como fetal, así como realizar un manejo multidisciplinar de esta patología.
ABSTRACT Background: The incidence of diabetes insipidus during pregnancy is approximately 1 in 30,000 pregnancies. Objective: We herein report a case of a patient with gestational diabetes insipidus occurring in our unit. We decided to communicate the case and review the literature regarding management and treatment options. Case report: A 38-year-old woman at 32 week of pregnancy with polyuria, polydipsia, and daily water intake of up to 7 liters. After performing the complementary tests and ruling out other more frequent conditions, the diagnosis of gestational diabetes insipidus was established. Conclusion: Gestational diabetes insipidus is a very rare entity that can cause a state of intense dehydration with hypernatremia and its consequent neurological impairment. Early detection is important in order to avoid complications of both mother and fetus, as well as to carry out a multidisciplinary management of this condition.

<p><b>Background</b>The outcome of pediatric deceased donor liver transplantation (LT) has not been well studied, especially pediatric deceased donor livers used in adult transplantation. This study aimed to evaluate the efficacy of LT using pediatric deceased donor livers and compare the outcomes between pediatric-to-pediatric LT and pediatric-to-adult LT.</p><p><b>Methods</b>A retrospective review of LT using pediatric deceased donor livers from June 2013 to August 2016 was performed. The patients were divided into the pediatric-to-pediatric LT group and pediatric-to-adult LT group based on the ages of the recipients. The survival and incidence of early vascular complications (VCs) were observed between the two groups. We also analyzed the risk factors of early VCs in pediatric LT and the effect of donor hypernatremia on the prognosis of recipients.</p><p><b>Results</b>There were 102 cases of LT using pediatric deceased donor livers in our hospital from June 2013 to August 2016, 83 pediatric-to-pediatric LT (recipients' age ≤13 years) and 19 pediatric-to-adult LT (recipients' age ≥19 years). The ratio of early VC was similar in the two groups (19.3% vs. 10.6%, P = 0.514). Low body weight of recipient was an independent risk factor of early VC in pediatric LT (odds ratio: 0.856, 95% confidence interval: 0.752-0.975, P = 0.019). The 1-year cumulative survival rates of grafts and patients were 89.16% and 91.57% in pediatric-to-pediatric LT and 89.47% and 94.74% in pediatric-to-adult LT, respectively (all P > 0.05). In all cases, patients using donors with hypernatremia (serum sodium levels ≥150 mmol/L) had worse graft survival (χ=4.330, P = 0.037).</p><p><b>Conclusions</b>Pediatric-to-pediatric LT group has similar graft and patient survival rates with those of pediatric-to-adult LT group. Low body weight of recipients is an independent risk factor of early VC in pediatric LT. Patients using donors with hypernatremia have worse graft survival.</p>

Background. Abnormal preoperative serum sodium measurements have been shown to be associated with increased postoperative mortality in US and European surgical populations. It is possible that such measurements are also associated with increased postoperative mortality in a South African (SA) setting, but this is yet to be confirmed. Establishing whether preoperative serum sodium measurements are associated with postoperative mortality could have implications for perioperative risk stratification in SA settings.Objectives. To determine whether preoperative serum sodium measurements are associated with postoperative mortality in SA surgical patients.Methods. This was an unmatched case-control study of patient data (demographics, comorbidities, procedure-related variables, and preoperative serum sodium measurements) collected during the South African Surgical Outcomes Study. Data were analysed using recommended statistical methods for unmatched case-control studies.Results. The study population comprised 103 patients and 410 controls. Cases were defined as patients who suffered postoperative inpatient mortality, while controls were defined as patients who did not suffer postoperative inpatient mortality. Preoperative hypernatraemia (i.e. a preoperative serum sodium measurement >144 mEq/L) was independently associated with a four-fold higher risk of postoperative inpatient mortality compared with a normal preoperative serum sodium measurement of 135 - 144 mEq/L (odds ratio (OR) 4.21, 95% confidence interval (CI) 1.19 - 14.83, p=0.025). Preoperative hyponatraemia (i.e. a preoperative serum sodium measurement <135 mEq/L) was not independently associated with a higher or lower risk of postoperative inpatient mortality compared with a normal preoperative serum sodium measurement (OR 1.39, 95% CI 0.70 - 2.76, p=0.346).Conclusions. Preoperative hypernatraemia, but not preoperative hyponatraemia, is a risk factor for postoperative inpatient mortality in SA surgical patients
